Residual Plots pattern and interpretation?

What are the types of residual plot pattern (i.e. fan, curved)?

How are outliers in residual plots interpreted?

How do I explain residual plots (explain the pattern, thats it?)?

Thank you

What information do you already have about the subject and what do you need?

I know that fan and curved patterns are bad. I'm doing an investigation for my class and i'm confused on how to interpret the graph.

I guess the purpose of a residual plot is to make sure that the data and graph is appropiate? I know that the residual is actual minus projected. But why is it relevant?

Not sure if that makes sense or if I worded correctly, but if I didn't, I'm happy to reword it.

Thank you
